Openwork Art Deco pendant in platinum and 18k (750 thousandths) white gold set with a beautiful rose-cut diamond in the centre, of fine colour and purity (approx. 6.10 mm in diameter). Around the central diamond, a geometric arrangement of small old mine diamonds and oval sapphires (chips). This jewel is probably the result of the transformation of an Art Deco brooch. Dimensions: 4.3 x 1.7 mm. Gross weight: 8.4 g.
